    摘要： Embodiments of the present invention provide a method and an apparatus for reminding a user based on a set position by using a mobile terminal. The method mainly includes: detecting, by a mobile terminal of a user by using a wireless network, that a distance between the mobile terminal and a set position is greater than a set value; and reminding, by the mobile terminal, the user of a set event according to a set reminding manner. The embodiments of the present invention can make full use of a WLAN function or a wireless communication function of a mobile terminal to determine, without any additional hardware, a position of a user by using a WLAN or a positioning system, thereby implementing a function of reminding the user.

    摘要： A video encoding device (e.g., a wireless transmit/receive unit (WTRU)) may transmit an encoded frame with a frame sequence number using a transmission protocol. The video encoding device, an application on the video encoding device, and/or a protocol layer on the encoding device may detect a packet loss by receiving an error notification. The packet loss may be detected at the MAC layer. The packet loss may be signaled using spoofed packets, such as a spoofed NACK packet, a spoofed XR packet, or a spoofed ACK packet. A lost packet may be retransmitted at the MAC layer (e.g., by the encoding device or another device on the wireless path). Packet loss detection may be performed in uplink operations and/or downlink operations, and/or may be performed in video gaining applications via the cloud. The video encoding device may generate and send a second encoded frame based on the error notification.

    摘要： Systems and methods are provided for adapting communication parameters to a variety of link conditions, traffic types and priorities. For example, WiFi transmission parameters (e.g. retry limit, AIFS, CW size, MCS order and/or CCA threshold) may be adapted to channel congestion levels, channel errors and/or traffic priority levels. Parameter adaptation may be coordinated across layers (e.g. between MAC and PHY layer parameters). Congestion levels may be detected, for example, using a smoothed queue size and/or channel busy time. Traffic may be transmitted using adapted parameters, such as reduced retry limits for a high congestion level and increased retry limits for priority traffic in response to channel error. Feedback may support parameter adaptation. For example, feedback may be provided by a receiver and/or within a sender, such as a sender MAC and/or PHY layer or a parameter adapter providing feedback (e.g. spoofed NACK packet) to a sender application, transport and/or network layer.

    摘要： Systems and methods are described for refining motion compensated predictions in block-based video coding. In an example embodiment, motion-compensated prediction is used to generate predicted sample values in a current block of samples. A precision difference value and a motion vector refinement for the current block are signaled in the bitstream. For each sample in the current block, a spatial gradient is calculated at the sample, and a scalar product is calculated between the spatial gradient and the motion vector refinement. The scalar product is scaled (e.g. bit-shifted) by an amount indicated by the precision difference value to generate a sample difference value, and the sample difference value is added to the predicted sample value to generate a refined sample value.
